Super Subtraction! 

Dahl class have been practising their subtraction skills over the last few weeks. 

They have really enjoyed playing the ‘Exchange Game’ with the dice and Diennes. Swapping ten single cubes for a ten stick whenever they reached a multiple of ten.

We have also been focusing on ‘finding the difference’ by using empty number lines and counting on in tens and then units to help us solve subtraction sentences.

Can you explain to someone at home how to find the difference between two numbers using an empty number line?
